Description

Die Erfindung betrifft eine Fußbekleidung mit einem mehrschichtigen Aufbau der Sohle nach dem Oberbegriff des Anspruchs 1. Das Dokument US 4874640 A offenbart diese Fußbekleidung. Während des Laufvorgang wird der Bewegungsapparat nicht unerheblichen Belastungen ausgesetzt. Viele Läufer, auch solche die keinen Leistungssport betreiben, entwickeln im Laufe der Zeit Knie- und Gelenkbeschwerden, die nicht nur beim Sport, sondern auch bei alltäglichen Betätigungen erhebliche Probleme bereiten können. Für Schuhe wurden daher Dämpfungselemente entwickelt, die diesen Belastungen entgegen wirken sollen.The invention relates to footwear with a multi-layer construction of the sole according to the preamble of claim 1. The document US4874640A discloses this footwear. During the running process, the musculoskeletal system is exposed to not inconsiderable loads. Many runners, even those who do not do competitive sports, develop knee and joint problems over time, which can cause significant problems not only in sports but also in everyday activities. Cushioning elements were therefore developed for shoes to counteract these loads.

Im Bereich der Laufschuhe sind verschiedene Dämpfungskonzepte entwickelt worden.Various cushioning concepts have been developed in the field of running shoes.

So wurde von der Firma Nike ein System entwickelt, das auf einer Luftsohle basiert. Ein mit Gas gefülltes Luftpolster wird dazu in die Sohle oder in Sohlenteile eines Laufschuhes eingearbeitet. Unter Belastung wird das Gas komprimiert und sorgt dergestalt für eine Dämpfung.For example, Nike developed a system based on an air sole. For this purpose, an air cushion filled with gas is worked into the sole or sole parts of a running shoe. Under load, the gas is compressed and thus provides damping.

Von der Firma Adidas ist ein Laufschuh bekannt, der Luft in Luftkammern eingeschlossen enthält, die durch dünne Strömungskanäle miteinander verbunden sind. Beim Laufvorgang wird die Luft durch die Strömungskanäle, je nach Belastung verlagert. Auch hier findet auf diese Weise eine Dämpfung statt.A running shoe is known from the Adidas company, which contains air enclosed in air chambers which are connected to one another by thin flow channels. When running, the air is shifted through the flow channels, depending on the load. Here, too, damping takes place in this way.

Von der Firma Reebok ist eine Sohle bekannt, in der Luft in einem Wabensystem aus Polyurethan eingeschlossen ist. Die Waben sind unterschiedlich groß und können so individuell bestimmte Teile des Fußes abstützen. Ein ähnliches System wurde von der Firma Puma entwickelt.A sole is known from the Reebok company in which air is enclosed in a honeycomb system made of polyurethane. The honeycombs are of different sizes and can thus individually support certain parts of the foot. A similar system was developed by the Puma company.

Alle diese Systeme haben den Nachteil, dass sie "federnd" eingestellt sind. Fersenpolsterungen führen beispielsweise zur direkten Drucksenkung während des Fersenkontakt zu Beginn der Standphase beim Gang nur am Aufprallpunkt der Ferse. Hierbei kommt es zur Umwandlung von kinetische Energie in statische Energie, die in dem komprimierten Gas in der Sohle gespeichert wird. Im weiteren Gangverlauf kommt es dann zur Kraftübertragung auf den gesamten Fuß und zum fortschreitenden Abheben der Ferse. Sobald die Ferse den Druck von der komprimierten Sohle nimmt, gibt diese die gespeicherte statische Energie als kinetische Energie wieder in das System des Fußes zurück. Dabei kommt es zu einem zusätzlichen Kraftimpuls in das Sprunggelenk.All of these systems have the disadvantage that they are "springy". Heel cushions, for example, lead to a direct reduction in pressure during heel contact at the beginning of the stance phase of gait only at the heel impact point. This converts kinetic energy into static energy, which is stored in the compressed gas in the sole. As the gait progresses, power is then transferred to the entire foot and the heel progressively lifts off. As soon as the heel takes the pressure off the compressed sole, the stored static energy is returned to the foot system as kinetic energy. This results in an additional force impulse in the ankle.

Durch diesen zusätzlichen Impuls in das Sprunggelenk wird zwar einerseits eine nicht unerwünschte Unterstützung des Laufvorgangs erzielt - es wird Energie zurückgewonnen - jedoch wirkt es dem eigentlichen Ziel, der Schonung des Gelenk- und Bewegungsapparat des Läufers, diametral entgegen. Tatsächlich entsteht eine nicht unerhebliche Mehrbelastung. Dabei ist das eigentliche Ziel solcher Dämpfungsmaßnahmen die Belastung des Bewegungsapparats zu vermindern.This additional impulse in the ankle joint does not undesirably support the running process - energy is recovered - but it works diametrically opposed to the actual goal of protecting the joints and musculoskeletal system of the runner. In fact, there is a not inconsiderable additional burden. The actual goal of such damping measures is to reduce the strain on the musculoskeletal system.

Zur Verdeutlichung des Problems sei darauf hingewiesen, dass die maximale Fersenbelastung beim einbeinigen Sprung das 3,5-fache des Körpergewichts betragen kann. Selbst beim normalen Gang wirkt eine Belastung von bis zu 130% des Körpergewichts auf die Ferse.To clarify the issue, the maximum heel load in a single-leg jump can be as much as 3.5 times body weight. Even with normal gait, a load of up to 130% of body weight acts on the heel.

Dementsprechend ist es Aufgabe der Erfindung, eine Fußbekleidung bereit zu stellen, die die beim Laufvorgang auf den Fuß, insbesondere die Ferse und den Vorfuß wirkende Energie wirkungsvoll absorbiert und abführt.Accordingly, the object of the invention is to provide footwear that effectively absorbs and dissipates the energy acting on the foot, in particular the heel and the forefoot, during the running process.

Diese Aufgabe wird mit einer Fußbekleidung nach Anspruch 1 gelöst.This object is achieved with footwear according to claim 1.

Die erfindungsgemäße Fußbekleidung kann eine Fußbekleidung beliebiger Art sein, beispielsweise ein Laufschuh, ein Schuh für den täglichen Gebrauch wie auch eine Sandale, etwa eine Freizeitsandale, wie sie unter der Bezeichnung Flip-Flop auf dem Markt ist. Der erfinderische Effekt der Dämpfung der Laufbewegung wird in allen derartig ausgestatteten Fußbekleidungen erreicht. Eine entsprechende Dämpfung kann auch mit einer Einlegesohle erreicht werden.The footwear according to the invention can be any type of footwear, for example a running shoe, a shoe for everyday use, or a sandal, for example a leisure sandal such as is marketed under the name flip-flop. The inventive effect the cushioning of the running movement is achieved in all footwear equipped in this way. A corresponding cushioning can also be achieved with an insole.

Die erfindungsgemäße Fußbekleidung weist einen mehrschichtigen, insbesondere dreischichtigen Aufbau der Sohle auf. In der Regel besteht sie aus einer Außensohle (Laufsohle), einer Innensohle (Brandsohle) sowie einer Zwischensohle. Erfindungsgemäß ist die Außensohle starrer als die Zwischensohle. Es können mehr als nur eine Zwischensohle vorhanden sein, wobei in jedem Fall eine der Zwischensohlen erfindungsgemäß gestaltet ist. Darüber hinaus können mehrere Innensohlen vorhanden sein, beispielsweise auch solche, die nur den Ballenbereich oder nur den Fersenbereich abdecken. Gegebenenfalls kann die Außenhaut der Zwischensohle zugleich auch als Brandsohle dienen bzw. die Brandsohle in die Zwischensohle integriert sein.The footwear according to the invention has a multi-layer, in particular three-layer, structure of the sole. It usually consists of an outsole (outsole), an insole (insole) and a midsole. According to the invention, the outsole is more rigid than the midsole. There may be more than one midsole, in each case one of the midsoles being constructed in accordance with the present invention. In addition, there can be several insoles, for example those that only cover the ball area or only the heel area. If necessary, the outer skin of the midsole can also serve as an insole or the insole can be integrated into the midsole.

Die Zwischensohle ist elastisch ausgestaltet und erzeugt den erfindungsgemäßen Dämpfungseffekt.The midsole is designed to be elastic and produces the cushioning effect according to the invention.

Dazu besteht die Zwischensohle aus einem Schaumstoff mit einer offenen Zellstruktur. Die Zellstruktur ist mit einem flüssigen Medium befüllt und einer gas- und flüssigkeitsdichten Außenhaut umgeben. Die offenzellige Struktur des elastischen Materials erlaubt es dem Medium, sich innerhalb der Zwischensohle zu verlagern und so einen Teil der Belastung, insbesondere der Ferse, abzufangen. Geeignete Schaumstoffe sind die aus der Kunststofftechnik bekannten Schäume, etwa aus Polyethylen, Polypropylen, Polystyrol, PET und Polyurethan.The midsole consists of a foam with an open cell structure. The cell structure is filled with a liquid medium and surrounded by a gas and liquid-tight outer skin. The open-cell structure of the elastic material allows the medium to shift within the midsole and thus absorb part of the load, especially on the heel. Suitable foams are the foams known from plastics technology, such as those made from polyethylene, polypropylene, polystyrene, PET and polyurethane.

Die Zwischensohle ist erfindungsgemäß aus einem Material im Integralschaumverfahren herzustellen dergestalt, dass Außenhaut und Zellstruktur aus einem einheitlichen Material bestehen.Besonders bevorzugt sind Zwischensohlen aus integral verschäumtem Polyurethan, die dadurch automatisch eine geschlossene Außenhaut und einen zelligen Kern aufweisen. Ein weiteres besonders gut geeignetes Material ist Polyester-Urethan-Kautschuk, der sehr gute elastische Eigenschaften aufweist.According to the invention, the midsole is to be made from a material using the integral foam process in such a way that the outer skin and cell structure consist of a single material. Midsoles made from integrally foamed polyurethane are particularly preferred, which automatically have a closed outer skin and a cellular core. Another particularly well suited material is polyester urethane rubber, which has very good elastic properties.

Eingesetzt werden können beispielsweise Materialen mit einem Raumgewicht von 40 bis 100 kg/m3. Die Porengröße beträgt 0,5 bis 5 mm zweckmäßigerweise 0,5 bis 3 mm. Das Raumgewicht des Schaums wie auch die Porengröße haben Einfluss auf die Dämpfungswirkung dadurch, dass eine geringe Porengröße dem in der Schaumstruktur fließenden Fluid einen größeren Reibungswiderstand entgegensetzt. Damit können über die Porengröße Zwischensohlen hergestellt werden, die den individuellen Bedürfnissen des jeweiligen Käufers angepasst sind. Es können auch Flüssigkeiten und Gas gemeinsam eingesetzt werden.For example, materials with a density of 40 to 100 kg/m3 can be used. The pore size is 0.5 to 5 mm, suitably 0.5 to 3 mm. The density of the foam as well as the pore size have an influence on the damping effect in that a small pore size opposes a greater frictional resistance to the fluid flowing in the foam structure. This means that midsoles can be produced via the pore size that are adapted to the individual needs of the respective buyer. Liquids and gas can also be used together.

Als Flüssigkeiten kommen insbesondere Wasser, Öle oder auch Alkohole in Frage, wie auch Mischungen mehrerer Flüssigkeiten, etwa von Wasser und Polyolen. Als Öle können pflanzliche wie mineralische Öle, aber auch synthetische Öle eingesetzt werden, etwa Silikonöle. Mehrwertige Alkohole, die geeignet sind, sind beispielsweise Glykole, auch oligomere Glykole, wie auch Glycerin. Wird Wasser eingesetzt, kann dies mit einem Verdickungsmittel verdickt werden, um die Viskosität zu erhöhen. Dies gilt auch für andere Flüssigkeiten. Über die Viskosität der in der Zellstruktur zu verlagernden Flüssigkeit kann der Dämpfungseffekt ebenfalls gesteuert werden. Es versteht sich, dass die erfindungsgemäße Zwischensohle auch teilweise mit einem gasförmigen und teilweise mit einem flüssigen Medium gefüllt werden kann. Als Gase kommen dabei in erster Linie Luft, Stickstoff CO2, aber auch Edelgase in Frage.In particular, water, oils or also alcohols come into consideration as liquids, as well as mixtures of several liquids, for example of water and polyols. Vegetable and mineral oils, but also synthetic oils, such as silicone oils, can be used as oils. Polyhydric alcohols that are suitable are, for example, glycols, including oligomeric glycols, such as glycerol. If water is used, it can be thickened with a thickener to increase viscosity. This also applies to other liquids. The damping effect can also be controlled via the viscosity of the liquid to be displaced in the cell structure. It goes without saying that the midsole according to the invention can also be partially filled with a gaseous medium and partially with a liquid medium. The primary gases to be considered are air, nitrogen CO2, but also noble gases.

Zum Befüllen/Nachfüllen weist die Zwischensohle seitlich ein Ventil auf.The midsole has a valve on the side for filling/refilling.

Die erfindungsgemäße Fußbekleidung weist die Zwischensohle mit der Zellstruktur vorzugsweise zwischen der Außensohle und Innensohle auf, wobei sie vollständig eingeschlossen ist. Dies schützt zum einen die Zwischensohle vor Beschädigung, erlaubt aber zum anderen eine einfache Fertigung, da die Zwischensohle nicht mit den anderen Sohlen vernäht werden muss. Es versteht sich, dass Außensohle, Innensohle und Zwischensohle miteinander verklebt oder auf andere Weise miteinander verbunden sein können.The footwear of the present invention preferably has the midsole with the cellular structure between the outsole and the insole, completely enclosing it. On the one hand, this protects the midsole from damage, but on the other hand it allows for simple production, since the midsole does not have to be sewn to the other soles. It goes without saying that the outsole, insole and midsole can be glued together or connected to one another in some other way.

Die erfindungsgemäße Fußbekleidung kann zusätzlich Polsterelemente aufweisen, die beispielsweise in Eintiefungen der Innensohle, insbesondere im Fersen- und/oder Ballenbereich angeordnet sein können. Hierzu können in diesen Eintiefungen Klettelemente angeordnet sein, mit denen diese Polsterelemente festgehalten werden. Diese Art der Einbringung hat gegenüber dem Verkleben den Vorteil, dass diese Polsterelemente nach Bedarf ausgetauscht werden können, auch um einen geringeren oder verbesserten Polstereffekt zu erzielen.The footwear according to the invention can additionally have padding elements which can be arranged, for example, in depressions in the insole, in particular in the heel and/or ball area. For this purpose, Velcro elements can be arranged in these depressions, with which these padding elements are held. Compared to gluing, this type of insertion has the advantage that these padding elements can be exchanged as required, also in order to achieve a reduced or improved padding effect.

Es versteht sich, dass die erfindungsgemäße Fußbekleidung im Übrigen normal gestaltet sein kann, d.h. mit in der Schuhindustrie üblichen Dekorelementen ausgestattet werden kann.It goes without saying that the footwear according to the invention can otherwise have a normal design, i.e. it can be equipped with decorative elements that are customary in the shoe industry.

Die Sohle der erfindungsgemäßen Fußbekleidung kann die übliche Form haben, d.h. absatzlos oder mit Absätzen versehen sein. Die Sohle kann elastisch und biegsam oder härter eingestellt sein oder auch konvex ausgebildet sein, sodass das Abrollen des Fußes erleichtert wird.The sole of footwear according to the invention may be of the usual form, i.e. heelless or heeled. The sole can be elastic and pliable or harder, or it can be convex, so that it is easier for the foot to roll over.

Mit der erfindungsgemäßen Fußbekleidung wird erreicht, dass der Initialkontakt der Ferse beim Gehen das in der Zwischensohle enthaltene Medium nach vorne in den Ballenbereich verdrängt. Dadurch wird der dämpfende Effekt beim Fersenkontakt erzielt. Beim Abrollen wird dann das Medium zurück in den Fersenbereich der Zwischensohle verlagert, wodurch der ursprüngliche Zustand wieder hergestellt wird und ein dämpfender Effekt beim Zehenabdruck zur Entlastung des Vorfußes beiträgt. Dieser Rückfluss des verdrängten Materials ist dabei langsamer, als die Abhebgeschwindigkeit der Ferse, was eine zusätzliche Belastung des Sprunggelenks vermeidet.With the footwear according to the invention it is achieved that the initial contact of the heel when walking displaces the medium contained in the midsole forward into the ball area. This achieves the cushioning effect on heel contact. When rolling, the medium is then shifted back into the heel area of the midsole, whereby the original state is restored and a cushioning effect on the toe-off helps to relieve the forefoot. This return flow of the displaced material is slower than the lift-off speed of the heel, which avoids additional stress on the ankle.

Beim Laufvorgang kommt es zur Verteilung des fluiden Mediums zunächst aus dem Fersenbereich in den Ballenbereich des Fußskelettes, der als nächstes belastet wird. Dies unterstützt die Lastübernahme durch den gesamten Fuß, von der Ferse bis hin zum Ballen und in dem Zehenbereich. Selbst der Großzeh und das Großzehengrundgelenk tragen beim Abheben einen Teil der Belastung. Grundsätzlich wird also der Gelenkapparat des Läufers weniger belastet, nicht zusätzlich.When walking, the fluid medium is initially distributed from the heel area to the ball area of the foot skeleton, which is the next to be loaded. This supports the transfer of the load through the entire foot, from the heel to the ball of the foot and in the toe area. Even the big toe and the metatarsophalangeal joint carry part of the load when lifting. In principle, the joint apparatus of the runner is less stressed, not additionally.

Die Erfindung wird durch die beiliegenden Abbildungen bevorzugter Ausführungsformen näher erläutert. Es zeigen:

Fig. 1
eine Draufsicht auf eine erfindungsgemäße Sandale;
Fig. 2
die Sandale von Fig. 1 seitlich von der Zehenseite her; und
Fig. 3
die Sandale von der Fig. 1 seitlich von der Fußinnenseite her.
The invention is explained in more detail by the accompanying illustrations of preferred embodiments. Show it:
1
a plan view of a sandal according to the invention;
2
the sandal of 1 laterally from the toe side; and
3
the sandal from the 1 laterally from the inside of the foot.

Die Sandale 1 gemäß Fig. 2 weist eine Zwischensohle 2 auf, in die ein Ventilelement eingelassen ist. Das Ventilelement 7 dient zu Erstbefüllung und ggf. zur Ergänzung und zum Austauschen des fluiden Mediums in der Zwischensohle. das Ventil 7 ist vorzugsweise selbstschlie-ßend ausgelegt, kann aber auch mit einem Stopfen verschlossen werden oder zugeschweißt werden. Im letzteren Fall ist eine erneute Befüllung ausgeschlossen.The sandal 1 according to 2 has a midsole 2 into which a valve element is embedded. The valve element 7 is used for initial filling and, if necessary, for supplementing and exchanging the fluid medium in the midsole. the valve 7 is preferably designed to be self-closing, but it can also be closed with a plug or welded shut. In the latter case, refilling is excluded.

Die Sandale selbst weist ein Riemenkonstrukt 6 zur Festlegung am Fuß des Trägers auf, das über zwei hintere Halterungen 4 und eine vordere Halterung 5 in dem Sohlenkonstrukt 2/3 verankert ist. Die Halterungen 4 und 5 ragen durch die Zwischensohle 2 hindurch in die Außensohle 3 und sind in der Außensohle 3 durch tellerförmige Erweiterungen 8 (siehe Fig. 2/3) verankert. Es versteht sich, dass die Halterungen 4 und 5 in Kanälen, die durch die Zwischensohle 2 geführt sind, verlaufen, so dass eine fluiddichte Abschirmung gegen das in der Zwischensohle 2 geführte fluide Medium gegeben ist.The sandal itself has a strap construct 6 for attachment to the foot of the wearer, which is anchored in the sole construct 2/3 via two rear mounts 4 and a front mount 5 . The brackets 4 and 5 protrude through the midsole 2 into the outsole 3 and are in the outsole 3 by plate-shaped extensions 8 (see 2/3 ) anchored. It goes without saying that the mounts 4 and 5 run in channels that are routed through the midsole 2, so that a fluid-tight shielding against the fluid medium routed in the midsole 2 is provided.

Die Halterung 5 mit dem Steg 9 befindet sich im vorderen Bereich der Sandale und ist so angeordnet, dass der Sandalenträger den Steg 9 mit dem großen und dem zweiten Zeh greifen kann. Der Steg 9 ist mit dem Riemenkonstrukt 6 verklebt oder vernäht und reicht mit der Halterung 5 durch das Sohlenkonstrukt 2/3 hindurch zur tellerförmigen Erweiterung 8 der Halterung 5 in der Außensohle (3).The holder 5 with the bridge 9 is located in the front area of the sandal and is arranged in such a way that the sandal wearer can grip the bridge 9 with the big and the second toe. The web 9 is glued or sewn to the belt structure 6 and extends with the mount 5 through the sole structure 2/3 to the plate-shaped extension 8 of the mount 5 in the outsole (3).

Es versteht sich, dass die tellerförmigen Erweiterungen 8 der Halterungen 4 und 5 an der Unterseite (Außensohle 3) und Oberseite (Zwischensohle 2 oder gegebenenfalls einer Innensohle) in die Sohle eingetieft sind, d.h. nicht hervorstehen.It goes without saying that the plate-shaped extensions 8 of the holders 4 and 5 on the underside (outer sole 3) and upper side (midsole 2 or optionally an insole) are recessed into the sole, ie do not protrude.

Fig. 2 zeigt die Sandale gemäß Fig. 1 von der Zehenseite her. Zu erkennen sind die Zwischensohle 2 und die darunter angeordnete Außensohle 3, wobei die Außensohle seitlich um die Zwischensohle 2 herumgezogen ist. Auf diese Art und Weise bewirkt die Außensohle 3 einen seitlichen Schutz der Zwischensohle 2. Dargestellt ist auch das Ventil 7 in der Zwischensohle 2. 2 shows the sandal according to 1 from the toe side. The midsole 2 and the outsole 3 arranged underneath can be seen, the outsole being pulled laterally around the midsole 2 . In this way, the outsole 3 provides lateral protection for the midsole 2. The valve 7 in the midsole 2 is also shown.

Das Riemenkonstrukt 6 ist über die Halterungen 4 im Fersenbereich in der Aussensohle 3 verankert, wobei sich im Bereich der Außensohle tellerförmige Erweiterungen 8 befinden, die in die Außensohle 3 eingelassen sind. Die Halterungen 4 und 5 werden über diese tellerförmigen Erweiterungen 8 in der Außensohle 3 gehalten. Dabei können die Teller 8 mit der Außensohle verklebt oder verschweißt sein.The belt construction 6 is anchored in the outsole 3 in the heel area via the holders 4 , plate-shaped extensions 8 being embedded in the outsole 3 and being located in the area of the outsole. The brackets 4 and 5 are held in the outsole 3 by these plate-shaped extensions 8 . The plates 8 can be glued or welded to the outsole.

Zu erkennen ist, dass die Halterungen 4 und 5, wobei letztere in den Steg 9 übergeht, in der Zwischensohle angeordneten Kanälen verlaufen, die die Abschirmung im Hinblick auf die Befüllung der Zwischensohle bewirken. Der Steg 9 ist mit dem Riemenkonstrukt verklebt oder vernäht.It can be seen that the holders 4 and 5, the latter merging into the web 9, run through channels arranged in the midsole, which cause the shielding with regard to the filling of the midsole. The web 9 is glued or sewn to the belt structure.

Fig. 3 zeigt die Sandale von Fig. 1/2 in seitlicher Ansicht von der Fußinnenseite her. Zu erkennen ist das Riemenkonstrukt 6 und mit dem Steg 9, die Zwischensohle mit dem Ventil 7 sowie die Halterungen 4 und 5 mit den Haltetellern 8. Zu erkennen ist auch, dass die Außensohle 3 im Bereich der Zehen und der Ferse seitlich an der Zwischensohle hochgezogen und damit auch im vorderen und hinteren Bereich einen Schutz der Zwischensohle 2 bewirkt. 3 shows the sandal from 1/2 in lateral view from the inside of the foot. The belt construction 6 and the web 9 can be seen, the midsole with the valve 7 and the brackets 4 and 5 with the holding plates 8. It can also be seen that the outsole 3 is pulled up laterally on the midsole in the area of the toes and the heel and thus protects the midsole 2 in the front and rear area as well.

Es versteht sich, dass die dargestellte Sandale nur ein Ausführungsbeispiel ist. Die erfindungsgemäße Fußbekleidung kann gleichfalls als konventioneller Schuh ausgebildet werden, wie auch als Slipper mit offenem oder geschlossenem Fersenbereich. Die Außensohle kann im Fersenbereich in einen Absatz übergehen, sie kann auch, zur Förderung des Abrollmechanismus mit einer Wölbung im zentralen Bereich ausgestattet sein. Wesentlich ist, dass die Zwischensohle 2 so ausgebildet ist, dass beim Abrollen des Fußes eine durch die Laufbewegung induzierte Verschiebung des fluiden Mediums in der Zwischensohle stattfindet.It goes without saying that the sandal shown is only an exemplary embodiment. The footwear according to the invention can also be designed as a conventional shoe or as a slip-on shoe with an open or closed heel area. The outsole can transition into a heel in the heel area, it can also be equipped with a bulge in the central area to promote the rolling mechanism. It is essential that the midsole 2 is designed in such a way that when the foot rolls off, a displacement of the fluid medium in the midsole induced by the running movement takes place.
